# Function storage_no_init

Module: `noir_aztec::macros::storage`

```rust
pub comptime fn storage_no_init(s: TypeDefinition)
```

Same as `storage`, except the user is in charge of providing an implementation of the `init` constructor function with signature `fn init<Context>(context: Context) -> Self`, which allows for manual control of storage slot allocation. Similarly, no `StorageLayout` struct will be created.

The contract's storage is accessed via the `storage` variable, which will will automatically be made available in all functions as an instance of the struct this macro was applied to.

Only a single struct in the entire contract can have this macro (or storage_no_init) applied to it, and the struct has to be called 'Storage'.
